Application filed AugustiBO, 1920. S erialNo. 406,919;

To allwhom it mag concern; 1

Be it known that I, ARTHUR J. Hown, a citizen of the United States, residing at Lakewood, in the county of. Cuyahoga and State of Ohio, have invented a new and .useful Caster-Wheel, of which the follow ing is a'specification. V TlllS invention relates to improvements 1n caster-wheels, and pertains more especially to a casterswheel having a removable rim whlch has circumferentially extending s1de flanges and an elastlc and compresslble solid tire between'said flanges.

The objectof this invention is to fac1l1-- tate the assemblage of the'component parts n of a caster-wheel of the character indicated,

to render thewheel simple and durable in construction, to have theherembefore mentioned tired rim conveniently removable from the body of the wheel for renewal or repairs, and to-efficiently. andlmexpensiyely hold said rim in plac'eon saidbody.

With this object in view, and to attain any other object-hereinafter appearing, this invention consists in certain features of conrangementsof parts, hereinafter described in this specification, pointed out the claims,and illustrated in the accompanying drawings.- V a a In said drawings, Figure l. is an elevation of a caster-wheel embodying my invention. F ig. 2 is'a central section taken along the line. 2-2, Fig. '1,"looki n in the direction indicated by thearrow. jig. 3 is a vertical :1 section taken along the line 3-3, Fig. 2,

. preferably substantially looking in the direction indicated by the arrows. I Referring .;to said? 'drawings, -5 indicates the circularbody of'my improved casterwheel.-iSaid bodyis preferably jQf H13i32Ll andhasa central-hole 6 for receiving an axle (not shown). Saidv body is provided at one end face 7 .thereof with an external circumferentially extending annular flange the. other end face 90f the body and farther from said flange than from the lastmentioned :face, with three cavities 10 spaced q id s a tly' r: cumferentiallyof-the bod i Y The body 5 is provided at each cavity 10 f with a rece'ss 12 which extends to said'cavit'y. from the adjacent end face 90f the body and; has a sloping wall113 "which extends the flange 8' on the from said face to said cavity; The wall 13; s

of each recess 12 faces in the direction-of; the adjacent endface!) of; the body and toward the outer circumference of the body, and the cavity 10 adjacent-said recess'ghas;

wall.

The flange s of the was an mar;

mentfor ,a metal rimiwhich p referablycon-fl 1 sists of a metal. channel-member -;be nt into substantially circular form and united to-- getherat the ends in any approved, manner and. comprising a base portion 15 of a cy-o lindrioal shape and also two laterally spaced;

outwardly projecting, circumferentially ex.- tending s1de flanges 16 and 17 The-flange 16 of the rim abuts againstthe, inner, side of the flange 8 of the body ..-;T he base; portion 15- of the rim; is mounted onjand surrounds and closely embracesthe-body-f) V between the end faces 7 and 9 of the body; Sald rim is provided with an annular tire 18 composed preferably of elastic and compressible material such,-for instance, as rub-- her, and applied to the rim between the flanges 16 and. '17 and fixed in place in any approved manner. I y f -The tired rim is provided at eachcavity 10 with a concaVo-convex inwardly offset; portion 19engaging said cavity, and the .in-'

ner extremitygof;the 'slopingwall13 of the recess 12 extending to said cavity is farther from. the axis of the wheelthan said cavity: engaging member 19 of the rim It willfbe observed therefore that the tired is shown provided with three members 19 i which project into the body 5 and are .s aced substantially equidistantly tially of the body.

circum eren- ,As already -hereinbefore indicatedi the tired rim-has its flan e 16 abuttingagainst ibody 5,' and .IQwould; here remark that said rimisshown 11pmvided: adjacent itsother flange 17 with three are spaced preferably substantially eqllidis; tantly circmnferentiallyflof the axisof the whe 'l nd i er a elwi h th ca t in the rim; and the body ehas. its end face 9,

radially inwardly projecting ears 20 which from which the recesses l2 .exten dfto said. cavities as; herelnbefore ind1cated, overlapped bysaid ears. Preferably said ears are formed by parts struck or displaced from the base;portion 15 of -the The rim'is shown positively secured to the body 5, preferably removably by screws extend-- ing through screw-receiving holes 21 in the ears 20 and having heads 22 countersunk in said cars at the outer sides of the: earS..- Each screw (see Fig. 2) has a threaded. shank 23 shown-f parallel with the central hole 6 in the body and engaging a correspondingly threaded hOlG'Qi-"lll the I body.

As the inner or cavitymeeting extremities of the sloping walls 13 are farther from the bottoms of the cavities 10 than the projecting members 19 of the rim, any force tending to displace the rimin' the'dir'ection in which the hereinbe'forey mentioned screws; are withdrawable from the body is op posed independentlyof the screws. '"How ever, the concavo-convex contour of said members 19 and the fresilienceof the' rimat are just wide enough to permit the'projectsaid members 19 are adequate to permit removal' of the rim, by force, from the body 5, upon the removal of the aforesaid screws; To efficient-lyprevent c'ircumferentlal (118* placement of'the rim independently of the;

body 5 is; of -vastimportance; By my im proved construction, in which" the members 19 project into said body, any likely-force tending; to displacethe rim circumferentially independently of the body is jeflicientlyopposed, and strain by such force on the aforesaid screwsa'nd on the ears 201s prevented. I I f Preferably the body 5"is' beveled, as at 25',

' between the outer endsof the recesses12 at the outer circumference of the adj acent end face 9 of the body to facilitatethe apphca f tion of the rim; freferably'the recesses 12 ing members 19 i to move endwise therethrough during the assemblage-ofthe parts} and obviously the slopingwal1s'13formguides for said members 19 ;during the as semblage of the; parts, and the r'elativearfrangement of the parts issuchthat when,

durlng the assemblage of'the' pa'rtsy-said members 19 have'come'into engagement withthe cavities 10 the screw-receiving holes-21 inthe ears 20 shall register with'the screwl'1o1es24inthe bo'dy.
